IMPROVEMENT IN FAS-TENINGS FOR SEAT-SPRINGS.

Specification forming part of Letters Patent No. 198,930, dated January8, 1878 application filed I June 25, 1877.

' city of Chicago, in the county of Cook and State of Illinois, haveinvented a new and Improved Fastening for Seat-Springs; and I herebydeclare the following to be afull, clear,

and exact description thereof, reference being had to the accompanyingdrawings, of which- 'Figure 1 is a perspective view, and Fig. 2 acentral longitudinal section.

My invention relates to an improved mode of fastening fiat springs ofcircular or elliptical form, such as are now much used for carseats,sofas, chairs, beds, and the like, to the slats upon which they rest.

Hitherto the custom has usually been to place the spring at the pointwhere its ends meet or lap between two slats, and firmly fasten thelatter together. This mode, however, though giving the requiredfirmness, is cumbersome, inconvenient, and expensive.

My object, therefore, is to provide a device which shall be free fromthese disadvantages, and yet be quite as effective in every respect.

My invention consists in securin g the spring to the slat by means of astrip of metal of such length that when placed across the spring itsends project beyond the edges thereof, which strip is riveted at itscenter to the spring, and at its ends to the slat, all as hereinaftermore fully set forth.

Referring to the drawings, A is the spring, which is set upright uponand, across the slat B, the lapping ends being contiguous thereto. C isthe strip of metal, which is secured at its center to the spring bymeans of the rivet 1',

-wh ich passes entirely through the lapping ends, as clearly shown inFig. 2. This rivet is made to serve the additional purpose of holdingthe lapping ends together, and is therefore driven before the spring isplaced in position upon the slat.

73 i are the rivets or bolts which secure the ends of the metal strip tothe slat; and as these should be adaptedto hold the said strip withgreat firmness, I deem it best to have the above-described mode offastening alone.

What I claim as new, and desire to secure by Letters Patent, is-

The herein-described device for fastening the spring to the s1 ,3:consisting of the trans verse strip of metal C, of such length that itsends project beyond the edges of the spring, which strip is riveted atits center to the spring, the rivet passing through the lapping endsthereof, and bolted, screwed, or other wise secured to the slat at itsends, substantially as specified.
